If you're looking for a spot in a shop, my advice would be to find one that's hiring, and put in an application.
While you're waiting for them to contact you for an interview, try to get a feel for the shop and it's clientele. Are they geared towards hunters? Maybe more of the tactical set. Or perhaps it's a do-all sporting-goods type store. Whatever the case, try to know what you're talking about going in - having special skills or knowledge that relates to the owner's customer base is a good thing to have.
Other than that, just keep pounding the pavement looking for openings. Be respectful, but persistent. Good luck!
